Super cool game! I think this game captures the Castlevania style very well. The jump feels a little heavy but I'm not sure if that's intentional. I also lost a run because my game got stuck in a black screen after dying. Only the UI was showing and I could still enter the menu, but I couldn't see any of the game screen. My character was still moving and attacking as I can hear the dagger bounce off the walls. So maybe the black screen transition just wasn't able to disappear?
Other than that bug, I had a lot of fun!
